OEX Alternator 12V 150A Hitachi Style High Output - HXA199HO

The OEX HXA199HO is a new 12V alternator rated at 150A, built in a Hitachi style with an internal regulator and twin leg mount. It is listed as a high output replacement and is intended as an upgrade from an original 90A unit, with the cable and fuse included for the upgrade.

This alternator suits units made by Hitachi and carries a 7 groove pulley with a 60mm outside diameter. Key mounting details include an M8x1.25 adjusting hole diameter and 169mm mount centre to centre, so matching the physical layout is just as important as matching the electrical rating.

The listed application is Nissan Patrol Gen5 Y61 GU 3.0L ZD30DDTi from 04/00 to 03/07. If you are replacing an alternator on that vehicle, checking the part number HXA199HO, the mount style, pulley, and wiring provisions before ordering will help avoid delays and unnecessary returns.

Application and Buying Notes

Before ordering, compare the vehicle application, part number HXA199HO, and the mounting layout on the original alternator. This unit is described as a Hitachi style alternator with a twin leg mount, 7 groove pulley, 60mm pulley outside diameter, and 169mm mount centre to centre, so those details need to line up with the vehicle already in the bay.

The 150A output is a meaningful step up from the original 90A unit listed for this application. That can be useful where the vehicle has additional electrical demand, but the alternator should still be matched to the existing charging system and wiring arrangement. The included cable and fuse are part of the upgrade package, which helps when moving from the lower output unit to this higher capacity replacement.

Because this is a new alternator with an internal regulator, the physical and electrical match matters more than the vehicle name alone. Confirm the unit make is Hitachi style, check the pulley section is 7 groove, and verify the adjusting hole diameter is M8x1.25 before committing to the purchase.

For commercial use, the listed warranty is 1 year, while passenger use is 3 years. Warranty terms are useful to know, but they do not replace fitment checks. If the original alternator differs in mount type, pulley configuration, or regulator arrangement, stop and compare those details first.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number HXA199HO helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 150 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include NISSAN NAVARA, NISSAN NAVARA 2001, NISSAN NAVARA 2002, NISSAN NAVARA 2003. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment by checking part number HXA199HO, the Nissan Patrol Gen5 Y61 GU 3.0L ZD30DDTi 04/00 - 03/07 application, and the physical details including twin leg mount, 7 groove pulley, 60mm pulley outside diameter, and M8x1.25 adjusting hole diameter before ordering.
